TRIPPING- MEHANISM FOR PRINTING-PRESSES.

Speciicaticn of Letters Patent. Patented Apr. 15, 1919.,

Application led March 28, 1917. Serial No. 157,979.

vnisms for printing presses having particular relation to tripping mechanisms for rotary printing presses or presses in which, during the normal operation thereof, the impression elements are not moved out of and restored back into impression relation during each cycle of operation, and has for one of its objects to provide an improved press actuated mechanism for tripping and restoring the impression elements of the press which is adapted to perform its'functions in avery efficient manner, the mechanism being` so designed that the movable impression member, or cylinder, is within the com plete` control of the press actuated mechanism at` all times during the movement of the impression element out'of and into impression or printing position whereby all shock or chattering of the mechanism which might result from the impression element and -its related. mechanism moving ahead of the lpress actuated mechanism of its own accord, is prevented. This press actuated mechanism is complemented by a novel controlling mechanism adapted` to allow the press actuated mechanism to assume complete control of the movements of the impression member out of and into impression position, as above described.

Inasmuch as the press actuated means functions to trip and to restore in succession and in order that the same may keep complete control of the impression element as it is tripped and restored I have designed the mechanism so that the controlling mechanism operates upon the tripping elements and restoring elements of the press actuated mechanism to render them functionless at different times whereby each of said elements is allowed to assume operative position and function to and retain the impression element in timed relation with the opposite or restoring element during all times in which the impressionelement is being moved out of or into printing position.

Another object resides in' providing a sin- ,gie revolution cylinderhaving a press actuated mechanism of the. above described character adapted to trip and restore the cylinder in the same revolution in which it is tripped, the controlling mechanism having separate connection with the press actuated mechanism for controlling the tripping'and restoring functions of the same, whereby the cylinder may be `tripped for a single lmpression -and restored to printing position in the same revolution in which it was tripped, or may be tripped for a succession of impressions, without being restored for a portion of each cycle, the press actuated mechanism acting in either case as above described. To renderthe controlling mechanism easy to operate, it embraces a single mechanism, which, when in one position, is

adapted to be engaged by the press actuated means to render the same inoperative to trip, and, when in another position, is adapted, to be engaged by said press actuated means to render the same functionless torestore.

A further object resides in providing a' printing cylinder,l a complemental impression cylinder, inking mechanism for the printing cylinder substantially out' of inklng relation with said printing cylinder when it is in the position it assumes when it is tripped, and tripping-mechanism for the printing cylinder, the printing cylinder having a blank portion and the tripping mechanism being so timed that said blank portion ,is passing the engaging points of the impression cylinder land the inking mechanism with the printing cylinder when the cylinder is being moved out of and into printing position whereby the` print-ing surface is inked but once for every impression regardless of whether or not' the printing cylinder was tripped `previously to the impression.

A further object resides in providing a printing cylinder and tripping mechanism therefor together with inking mechanism and a complemental impression cylinder in animproved interrelation which, by reason of thefact that such interrelation allows sufficient time for all of the elements to properly perform their functions, may do 'so in a Very efficient manner and allow the fully described by reference tothe accompanyingdrawings showing the preferred embodiment thereof and in which Figure 1 is a view in side elevation, parts broken away, of a portion of a printing press equipped in accordance with the invention; Fig. 2 is an end view illustrating the arrangement ofgearin and cylinders which is preferred; Fig. 3 1s a sectional elevation illustrating parts that are disclosed in Figs. 1 and 2 and other parts in'addition, the printing and impression cylinders being -out of printing relation; Fig.` 4 is a view similar to Fig'. 3 excepting thatthe printing cylinder is in printing relation; and Fig. 5 is a view in end elevation, with parts in sectlon, of the tripping cam mechanism.

The power for operating the press 1s deyrived from a driving shaft 11u-pon which there is a driving spur pinion 2 upon one side and near one end T of the press. This v spur -pinion meshes with a spu-r gear`3 fixed upon a stub shaft 4 mounted inthe extension 5 boltedto the base of the press frame.`

The spur gear 3 meshes with a spur gear 6 mounted freely lupon a shaft 7 upon which shaft the impression cylinder 8 is fixed. The shaft 7 is journaled in boxes 71 that are contained in housings in the side frames of the press. These boxes' are normally fixed to give a fixed axis of rotatlon of the im. pression cylinder 8 but are vertlcallyadjustable by means of the adjusting screws 72.

The gear 9 is fixed upon shaft 7 and meshes with a spur gear 10 which is fixed upon a stub shaft 11 journaled in the extension 12 bolted. to the base. of the p ress frame. The spurr'gear 101 is co-a-xial with the spur gear 10 and is also fixed upon the stub shaft 11 by being bolted to the gear lOwith bolts 111. The spur gear 101 is in mesh with a spur gear 102 fixed with respect to the spur gear 6 by being xedly mounted upon the hub 61 of this latter gear. This hub 61 is journaled in a vertically adjustable bracket 121 carrled upon the extension 12. This gear 10 is a cylinder gear mounted at an end of the printing cylinder 13 but not in fixed relation to the shaft 14 of this cylinder 13. The cylinder shaft 14 is journaled in boxes 15 that are mounted for vertical movement between guides 16 upon the press frame 17, the vertically movable boxes permitting movement of the printing cylinder transversely to the axis of the cylinder gear 10 and the axis of the cylinders 8 and 13. The distance between the axes of the gears 9 and 10 is fixed as their shafts 7 and 11 have fixed axes of rotation. As the printin cylinder 13 is adjustable with respect to t e axis of its cylinder gear 10 flexible means are employed for connecting said cylinder gear 10' of the cylinder gear 10 to remain fixed while the axis of the cylinder may shift, this disk. or connectin means 18 being shiftable with respect to said cylinder 13 and said cylinder gear 10. The disk 18 carries two diametrically opposite slotted guideways 19 the slots of which receive the diametrically opposite driving blocks 20 that are carried bythe gear 10, these blocks 20 and the slots in the guideways 19 being upon the same diametrical line whereby the disk 18 may shift wit-h respect to the gear 10 along the diametrical. line containing the blocks 19. The disk 18 is formed with a groove 21 disposed along theldiametrical l1ne that is at right angles to the diametrical line containling the driving blocks 19 and guideways 20.

The groove 21 receives a rib 22 carried by the disk 23 and disposed on the diametrical line of this disk. The disk 23 is fixed with respect to the shaft 14 and the cylinder 13. By the means described for connecting the cylinder gear 10 with the printing cylinder 13 the peripheral speed of such cylinder will be malntained'the same as the peripheral speed of the cylinder gear 10 (which latter speed is measured at the pitch circle or driving line of thegear teeth) even though said cylinder and cylinder gear are laterally shifted relatively to one another causing relative displacement of their axes. While the printing cylinder 13 is in printing position itsaxis is preferably co-incidentwith the axis of the cylinder gear 10 but when the cylinder 13 is tripped out Aof printing position its axis is then non-coincident with the axis of its cylinder gear 10 but this cylinderl gear maintains its own A fixed axis so that the' meshing thereof with the driving gear 9 and driven thereby is not disturbed. The spur gear 9 meshes with spur gear 26 fixed upon shaft 25 journaled in the side frame 1:'. `The sheet transfer cylinder 24 is fixed upon the shaft 25. The driven gear 9 thus drives the spur gear 26 to rotate the sheet transfer cylinder 24 at the peripheral speed of the impression cylinder 8. In the press illustrated the cylinders 8 and 24 are each plural revolution cylinders and the cylinder 13 is a single revolution cylinder, each. of the cylinders 8 and 24 rotating two revolutions to each revolution of the cylinder 13.

The gear 101 meshes with intermediate gears 27 and 28 that are respectively in mesh with driving pinions 29 of two inking couples and the d-riving pinion 30 of another inking couple. The pinions 29 and 30 drive metal distributing rollers 31 (upon the shafts of which their driving inions are fixed\ which in turn drive the fdrm rollers 32,- these form rollers inking the printing surface of the printing element 131 of the printing cylinder 13. The ink is furnished from the ink supply roller 33 of the ink whereby vthe sheet Vtransfer cylinder 2 4 fountain not shown by way of the usual the pinion :2"drivesthe 'train of 'gears'ff 6 and as gear 6'- is iixed-with` respect to gear 102 this gear' 6 drives the train of gears including gears 102, 101, whichtrain of gears drivesthe twotrains 27,;29`and 28, 30.*' thegears 10y andi101 are in'lix'ed relation the gear 101 drives the trainof'gears that ini cludes the gears 9 and 10 whereby not only is the cylinder 13 turned but the cylinder'lS is also turned. lThe gear 9 of the trainof gears 9, 10 is in mesh with the spur gear 26 turned.

The: tripping'mechanism employed may be of the general nature illustrated in my Patent No. 550,992, dated'December 10, 11895, with necessary changes. `The footkey 40`is normally held up by a spring 41 and is connected by a bell crank 42.` with' a connecting link 43 that is'conneeted with a rocker arm 44 that in turn is fixed `upona rod 45 and on which rod there is fixed la cam arm 46 carrying a tri cam portion 47 .l Whenever theA foot key 1s depressed the rod 45 of the trip-v ping mechanism is turned to turn vthe cam arm 46 to move the upper end'of the cam arm, where said cam portion'47 is disposed downwardly and with it cam 47' to allow the hook 48 to come into engagement with-the tooth 49. The part'50 of hook 48, the rockmg dog 51,- which is pivoted on the rear side, of the arm'52 at 511 and the part 53 of tooth 49 constitute elements of a coupler that connects the' printing cylinder 13=Withits tripping cam 54. The tripping earn 54 is rotated by a gear 55 upon which the cam vis lixedlyilocated,`the gear 55 in turn being rotated by the pinion l56 which is*l mounted for rotation upon the stud 57 fixed to' the frame of the press. A gear 58 is iixedly 'mounted upon a shaft 581 which is journaled in the frame of the press, and a inion 571 is. also fiXedly mounted upon sha t'581 and meshes with the pinion 56. The shaft 1 passes through the machine from sideV to side'and has a pinion 59, vmeshing with the gear l'58, fixedlymounted on the end thereof opposite that upon which thepinion 2 Ameshing with gear 3, as hereinbefore" described, is carried. Thus the cam 54 is driven in timed relation with the cylinders which are driven by shaft 1 through pinion 2 and gear 3. The cam groove :60 in cam 54 engagesv a cam roller 61 upon the arrn525 loose'on shaft 62 thatpasses from Iside to side"o f"'the*machine andto which shaft thetooth 49 and the'stop finger the stud 63 upon theinner end owhichthe hook 48 is y'mni'n'ted toswin'g.y .The shaft? 62 carries tw eccentrics" 64'up`on each" ofwhich the sliding box `1`ne1vnber65a`res'ts,ef`tchl sliding .supports Athe lsprings 1661. These springs Supportv a: largepart vofthe weight of the member' Supporting' a 'U1-Shaped XtIicylinder 13,'there` being sufficient weight un- "n supported bythese'sprngs 'to cause the cylinderto descend when the eccentrics l64 are turnedto lower positions. The arc a b of the cam' groove 60 isconcentricwith respect to the shaft 67 of the cam'.l The cam roller 61 is not'bodilyl movedwhile engaging this part of the cam groove a, b whereby the arm 52 `is 'then at rest.' The 'hook :48 carries a' cam roller 68 that may bear upon the-operating'tripping cam portion 47 ofthe arm 46. The' arm 52 carries a stoppin 691 and hook 48 has a lug 70, the elements 69 4and' 70 preventing the hook 48 `from' separating any farther from the-tooth 49 than illustrated.y

Each pair of eccentrics 64 upon the same shaft 62 has the position illustrated in Fig. 4 When the prin-tingcylinder v13 is in its -normal operating posit-ion, -the centers of these eccentrics bein normally positioned slightly to the left o the vertical .line passing `throughthe centers of the'shaft 62 and the shaft of the printingcylinder and being between this line and the stationary stop pin 71. As tooth 49 is in' fixed relation to the eccentrics 64-'the stop pin 71 holds the shaft 62 from counter-'clockwise rotation to hold-the printing cylinder 13 in working position'.` The stop pin 71 illustrated is upon one side ofthe-press (Fig. v3). vThere may be a similar stoppin '711 on the `other side of the press that is to' be engaged 'by an arm 491 I( Fig. 1) fixed upon the other end of the shaft 62 and positioned similarly to the tooth 49 to take'part in preventing the turning of the shaft 62 and the eccentrics thereon.

`lVhen the shaft 62 is turned clockwise the eccentrics 64, being ixed'upon the shaft, are also 4turned clockwiseso that the printing cylinder is lowered to non-printing posiof the part 50 of the hook 48 with the tooth 49 can lonly occur while the areal portion a b of the cam groove 60 is passing by the cam roller 61l which is when the line b1 (shown on the cylinder 13, Fig. 3) has passed from the line a1 to the position of the line b1. This tripping may be e'ected at a time when the cylinder 13 is in a. printing position and only during the time the leading edge of the printingn form 131 travels through the arc a2 b2 and during the time the eccentric cam portion a3 of the cam lgroove 60 lying between the side b of the arc a b and the shaft 67 is passing by the roller 61 (Fig. 3). When the cam roller 61 is passing over the cam portion as of the cam groove 60 between the side b of the arc a lb and the shaft 67, the part 50 of the hook 48 (assuming that the attendant has pressed down the key 40 to drop the arm 46 to permit the hook 48 to engage' the tooth 49) pulls .the tooth 49 in a. clockwise direction (while the leading end of the form 131 is passing between the lines a2 b2) to permit the printing cylinder 13 to be lowered by its own weight (Fig.` 3). When the roller 61 is in the portion of the cam groove 60 between the shaft 67 and the side a of the arc a b (while the leading end of the form 131 is passing between the lines a* b4), the motion of the arm 52 is reversed, providing the foot key 40 had been previously released, whereupon the swinging extension 51 of the arm 52 pushes upon the lug 53 carried by `the tooth 49 lto turn this tooth and the eccentrics 64 fixed with respect thereto counter clockwise back to the normal position.

' .In coming back to this position the eccentries 64 raise the printing cylinder to workin position. It is to be understood that the lro ler 68 (upon hook 48) supports the hook while this roller6'8 rides over the tripping -cam portion 47lwhen the arm 46 that carries this cam 47 is in the normal raised position y and while the printing cylinder is in its norlco mal operating position. The cam arm 46 may be lowered at any time but should this arm be lowered while the roller 61 is not in the areal portion a b of the cam slo-t the swinging end of the hook will ride upon the crown of the tooth 49 until the roller 61 is received in the areal portion a b of said cam groove 60.

The cylinder 13 is maintained in `its tripped position, during any desired number of successive cycles of the machine or revolutions of the cylinder 13, without said cylinder necessarily returning to printing position during a. portion of each cycle of the machine or revolution of said cylinder, by the same foot key 40 that causes the cylinder 13 to be tripped. In order that the key 40 may serve this purpose it is in operating connection with a cam lever 402 that is pivotally mounted upon the frame of the machine, the connection of the foot key with the cam lever 402 including a link 40s pivotally connected at one end with the lever 402 and at its other end with a-n arm of the bell crank 42. When the foot key 40 is depressed the lower end of the cam lever 402 is raised to be in the path of movement of and to engage the roller 405 (Fig. 3) carried by the rocking dog 51, whereby this rocking dog is raised and relieved 0f its function of coupling the actuated mechanism of cylinder 13 with such .cylinder to prevent this mechanism from raising the cylinder 13 to printing position. In performlng this function the dog 51 normally engages the part 53 of the tooth 49 and as the dog 51 is pivoted at 511 to the arm 5'2 the arm 52 is, through the. intermediation of the dog, engaged with the part 53 of the tooth 49. This dog thus, in its normal position, serves as a coupler for connecting the tripping mechanismvof cylinder 13 with the cylinder to enable such tripping mechanism to raise the cylinder 13 to printing position. When the lower end of the lever 402 is thus raised it lifts the dog 51 out of the' path of engagement of the portion 53 of the tooth 49, and/permits the dog to ride over such-tooth portion when the dog is swun by its operat- 105 ing cam 54. Thus the cylin er 13 is maintamed in its lowered position as long as the foot key 40 is depressed and only when the foot key is depressed long enough for this depressed key 40 whereby the cam 402 and parts connected therewith are maintained in the operating position shown lby Fig. 3 to keep thedog 51 from engaging the tooth portion 53.

From the above description it will be noted that I have provided press actuated mechanism adapted to trip and restore, the mechanism being ada-pted to assume operative position both to function to trip and to restore, together with controlling mechanism for said'mechanism adapted, when in 125 one position, to allow said mechanism to function to trip and while in this position to render said mechanism functionless to restore, said .controlling means, when in another position, being adapted to render the incense press actuated mechanism functionless to trip and to allow the same to function to restore, the controlling relation of said controlling mechanism being such that it is not operable in any of its positions to position either the tripping or restoring elements of said mechanism at a time When the opposite element' is performing kits function, r1`his is due to the fact that cams 47 and 1:02 can only engage their respective rollers 68 and 405 of the respective movable elements 48 and 51 to position the same just previous 4to the period when each respective element vy'ould function to move the cylinder, the tune in which said controlling mechanism is 1n engaging relation with the restoring mechanism being later than the time When it is in engaging relation with the tripping mechanism, said elements being uncontrolled by their respective cams during all other periods in the cycle of the machine and free to move under their gravital influence and assume operative position except as limited by the engagement of said elements With the crovvn of the tooth. 49 to prevent said elements from moving to operative position as hereinbeitore described.

llhus as the mechanism oscillates and trips the cylinder both of the elements i8 and 51 are engaged With the tooth 49 and prevent sai-d. tooth and its related mechanism from moving faster or-slovver than the cam 54 moves said elements 48 and 5l whereby any chattering of the mechanism or jar as the cylinder reaches its fully tripped position is prevented.. As the mechanism oscillates and operates to restore the cylinder to printing relation, both of said elements 48 and 51 are engaged with the tooth 49 in the same manner whereby an even movement of the cylinder and its related mechanism to printing position isialso assured. The controlling mechanism is alternately engageable with the tripping and restoring elements only at the opposite ends of the stroke of the oscillating movements of the same, and is only operable to control said mechanism relative to its 'tripping function when said mechanism is in its completely restoring position and adapted. to controlV said mechanism relative to its restoring function when said mechanism is in its completely restoring position and .adapted to control said mechanism relative to its restoring function when said mechanism is in its completely tripping position.

The sheets to be printed upon are fed to the impression cylinder 8 (Fig. 3) from the feed board or other feed structure 73 which is mainly located in the quadrant containing the inking mechanism and projects into the quadrant containing the impression cylinder. rl`he grippers 7-1 upon the impression cylinder 8 take the sheet, numbered 75, from the feed board carrying it through vthe line 76 joining the centers of the shafts 7 and 25 to the line 77 joining the centers of shafts 7 and 14a, whereupon. the first printing operation is initiated, the form 1.31 upon the printing cylinder 13 then. having printing relation with the sheet 75 upon the impres- V sion cylinder 8. A. ysheet, 78 (Fig. 3) upon the sheet transfer cylinder 24k is shown preceding the sheet 75, lsheet 78 being held by grippers 7 9 that hold the sheet during a revolution of the sheet transfer cylinder 24C after the grippers 79 receive the sheet from grippers 741ipreparatory to being transferred to the sheet delivery tapes 80. The first printing 'operation upon sheet 7 5 continues during the first revolution of the. impression cylinder 8 and a part of the second revolution thereof (beginning with thetime the impression cylinder 8 receives the sheet) until the form 131 upon the printing cylinder completes its printing upon the sheet 75. During the second revolution of the impression cylinder 8 the grippers 79 upon the sheet transfer cylinder 26 take the sheet 7 5 being printed upon by the form '131, the grippers 74 releasing the sheet and the grippers 7 9 taking the sheet when these grippers of cylinders 8 and 26 are adjacent the line 76 during the second revolution oi the impression cylinder 8. The transfer of sheet 75 from cylinder 8 to the sheet transfer.

cylinder 26 lvvill not occur until these cylinders have each made nearly one revolution from the position shown in Fig. 3, and at the'time grippers 74E again reach line 7 6.

rlhe inling mechanism is substantially included-in a quadrant of a lcircle having its center included in the normal axis of the printing cylinder and which quadrant is margined by the verticaldiametrical line 81 of such circle and along Which vertical diametrical line the printing cylinder moved when tripped out of printing position and When restored to printing posi.-

tion. The inking mechanism is normally unchanged in position so that When the printing cylinder is lovveredto non-printing position the printing cylinder., or form cylinder 13 is brought substantially out of inking relation With the inking mechanism. The printing or form cylinder is lowered out of printing position While the leading or Jfront end of the form 131 is traveling through the arc a2 b2. rlhe printing or form cylinder-*13 is raised into printing position during the time the front end of .the form passes through the arc at b4'. lt will be noted at this point that a relatively large blank or nonprinting portion 132 is provided on the cylinder 13 and lies between the lead.

ing and trailing ends of the form 1.31,' andl that the engaging points of the impression cylinder 8 and the inling mechanism With the printing cylinder 13 lie Within the circumferential extent of said blank portion isc 25 V than one revolution, the form 131 will not 132. The tripping and restoring movements of the cylinder 13 are so timed relatively to the abovementioned engaging points that this blank portion is substantially passing said engaging points While said cylinder is being tripped out of or restored into printing position. :While the trailing end of the form 131 is passing by the lower end -.ing end of the form 131 passes the lower ,end form rollers 32 but substantially does' l not engage the same as the restoring movement is not completed until said trailing portion has passed the same', .whereby the form 131 receives no further ink from the inking mechanism in the revolution in which the form or printing cylinder was tripped. If cylinder 13 should be tripped for more receive any-further ink in addition to that which it received .the last time before the cylinder Was tripped. The center of .the

impression cylinder 8 .and this cylinder itself are included in the next quadrant that is marginedv by the aforesaid diametrical line 81 and in the same half circle with the quadrant in which thek inking mechanism is disposed, this diametrical line dividing this half circle into such quadrants. The center'of the sheet transfer cylinder 2G and tliistransfer cylinder itself. are included in the same quadrant that contains the impression cylinder 8. The automatic mechanism for restoring the printing cylinder 13 to printing position performs this function during the same revolution in which this cylinder is tripped, if the foot key 40 is released at the proper time. This release of the foot key may occur immediately after the arc a b has passed the roller 61 and after the 'roller 68 has passed out of engagement With thel cam portion 47. The feed board overlies the printing cylinder, its inking mechanism, and a part of the impression cylinder.
